Automated README summary
Automatically summarized from the README on 13 Oct 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
An Elixir client that sends a state and typed questions to System One decision models and returns full probability distributions. It supports TypeSafe Jev, Cloudflare Clef, OpenAI Decisions, OpenRouter, and self-hosted endpoints, for routing and gating decisions.
How it uses Jev
Jev is one of the supported providers. You call SystemOneClient.evaluate(state, questions) with typed questions (noul, choice, score). Jev returns calibrated probabilities, e.g. a Choice answer with confidence and probabilities, a Noul answer with a noul value, or a Score answer with score and probabilities. The result is used in code for top-k, thresholds, or level cuts.

Technique worth stealing
Use full probability distributions from typed questions for routing and gating decisions.
Try it
Add {:system_one_client, "~> 0.1"} to deps, then call SystemOneClient.evaluate/3.
Model judgments from README excerpts
Project signals use repository metadata, an existing summary and the first 700 README characters, not the full project. “Not found” means not detected in that material; it does not establish absence. These are the original judgments with recorded models and dates, not source audits or run results.

Evidence
These signals use repository metadata, an existing summary and at most 700 cleaned README characters. ≥ 0.60 means reported in that excerpt; ≤ 0.40 means not found there. The middle band is inconclusive. None is a source-code audit or a test result. The runnable-tool question excludes research experiments; the recommendation question asks for a learning shortlist, not a quality verdict.
